Use simple C++. Implement a stack template class using a std::vector as underlying storage. Implement, push(), pop(), top(), and size(). Test using the given main()

#include

// Your stack class template class Stack { };

int main() { Stack s; s.push(1); s.push(2); s.push(3); s.push(1); s.push(2); s.push(3); s.pop(); s.pop(); s.push(5); s.pop(); s.pop(); s.pop(); // get the top (without popping) int x; s.top(x); std::cout << "The top is " << x << ". "; // 2 return 0; }
